Or does the thought of wandering around the shops fill you with terror?For some of us, shopping is an enjoyable way of spending our spare time and our money. For me, its something I would rather avoid. Thank goodness for the Inter! Its more convenient to buy CDs, electrical items, even food from the fort of your sofa. But thats not the only reason: price is an important factor. We can buy goods and services cheaper online. But sometimes the problem is knowing what to buy. This has led to a type of shopping called “showrooming”. Showrooming is something Ive done. I will go to a shop to see, touch and try out products but then go home and buy them online at a knock-down price. Im not alone in doing this. Research by a pany called Foolproof, found 24% of people showroomed while Christmas shopping in xx. Amy Cashman, head of Technology at TNS UK, says the reasons for this new shopping habit are that “people are lacking time, lacking money and they want security about the products they are buying ”. She explains that consumers are not only shopping online at home but they are using the Inter in store or on their smartphones to shop around. But does this mean technology will kill shops? Certainly shops will change. They will have to offer more petitive prices or encourage people to buy more by giving in-store discounts or free gifts. We mustnt forget that buying in a shop means you can get expert advice from the sales assistant and you can get good aftercare. Its good to speak to a real human rather than look at a faceless puter screen, but at least by showrooming, you get the best of both worlds! 1. The two questions in Paragraph 1 are raised to _. A. introduce the topicB. give two examples C. pare different opinionsD. get answers from readers 2. Aording to Amy Cashman, which is not the reason for showrooming? A. The lack of time. B. The fort of the sofa. C. The shortness of money. D. The security of the product. 3. The authors attitude towards showrooming is _. A. critical B. neutral C. casual D. supportive There is a very instructive incident involving the life of Alexander the Great, King of Greek. Alexander, after conquering many kingdoms, was returning home. On the way, he fell ill and it took him to his death bed. With death staring him in his face, Alexander realized his conquests, his great army, his sharp sword and all his wealth were of no consequence. So, he lay helplessly waiting to breathe his last. He called his generals and said, “I will depart from this world soon, and I have three wishes. Please carry them out without fail.” “My first desire is that,” said Alexander, “My physicians alone must carry my coffin.” After a pause, he continued, “Secondly, I desire that when my coffin is being carried to the grave, the path leading to the graveyard be spread with gold, silver and precious stones which I have collected.” The king continued, “My third and last wish is that both my hands should be kept hanging out of my coffin.” Alexanders favourite general kissed his hand and pressed it to his heart. “Oh, King, we assure you that your wishes will all be fulfilled. But tell us why do you make such strange wishes?”Alexander took a deep breath and said, “I would like the world to know of the three lessons I have just learnt. I want my physicians to carry my coffin because people should realize that no doctor can really cure any bodies. They are powerless and cannot save a person from the people not take life for granted.” “The second wish of spreading gold, silver and other riches on the way to the graveyard is to tell people that not even a bit of gold will e with me. I spent all my life earning riches but cannot take anything with me. Let people realize that it is just a waste of time to chase wealth.” “And about my third wish of having my hands hanging out of the coffin, I wish people to know that I came empty-handed into this world and empty-handed out of this world.” With these words, the King closed his eyes. Soon he let death conquer him and breathed his last. 4. The first paragraph suggests that Alexander _. A. wanted to leave the world as he came empty-handed B. realized that what he got in his life was nothing to him at all C. was spending a lot time conquering many kingdoms and had earned a great amount of wealth D. regarded his conquests, his great army, his sharp sword and all his wealth as the most important things 5. The underlined word “clutches” in Paragraph 4 means “_”. A. sentence B. attention C. control D. shadow 6. The author intends to _. A. tell us the story of Alexander B. stress the power of Alexander the Great C. persuade people to realized what Alexander said D. introduce readers to the instructive lessons of Alexander 7. What would be the best title of the passage? A. The Death of Alexander B. The Greed of Alexander C. Three wishes of Alexander D. The Life of Alexander A new study shows students who write notes by hand during lectures perform better on exams than those who use laptops. Students are increasingly using laptops for note-taking because of speed and legibility （清晰度）. But the research has found laptop users are less able to remember and apply the concepts they have been taught. Researchers performed experiments that aimed to find out whether using a laptop increased the tendency to make notes “mindlessly” by taking down word for word which the professors said. In the first experiment, students were given either a laptop or pen and paper. They listened to the same lectures and were told to use their usual note-taking skills. Thirty minutes after the talk, they were examined on their ability to remember facts and on how well they understood concepts. The researchers found that laptop users took twice as many notes as those who wrote by hand. However, the typists performed worse at remembering and applying the concepts. Both groups scored similarly when it came to memorizing facts. The researchers report said, “While more notes are beneficial, if the notes are taken mindlessly, as is more likely the case on a laptop, the benefit disappears.” In another experiment aimed at testing long-term memory, students took notes as before but were tested a week after the lecture. This time, the students who wrote notes by hand performed significantly better on the exam. These two experiments suggest that handwritten notes are not only better for immediate learning and understanding, but that they also lead to superior revision in the future. 8. More and more students favor laptops for note-taking because they can _. A. write more notes B. digest concepts better C. get higher scores D. understand lecture better 9. While taking notes, laptop users tend to be _. A. skillful B. tireless C. thoughtful D. mindless 10. The author of the passage aims to _. A. examine the importance of long-term memory B. stress the benefit of taking notes by hand C. explain the process of taking notes D. promote the use of laptops 11. The passage is likely to appear in _. A. a finance report B. a puter textbook C. a science magazine D. a newspaper advertisement If you dont think technology can improve your trip, meet Judy Williams. When she and her husband recently checked into Blu Hotel in Zurich, a clerk asked them to sign the dotted line on a room rate hundreds of dollars higher than their online offer. “It was not a cheap stay,” says Williams, a lawyer from Billings, Mont. But it became more of one after her husband fired up the Booking. app hed used to book their room on his smartphone. “As soon as we showed him the cost, he honored it,” Williams says. Technology may create challenges for travelers but it can also solve them. Its more than making sure of a hotel cost. The latest Booking. can help users select hotels by location, make a secure booking and view the confirmed (已確認的) cost so they never need to re-discuss their hotel price. Another pain point for travelers is traffic that eats away precious vacation time. Theres a new app called Commute which is aimed at users who have to make the same trip every day. But if youre headed to Los Angeles or Honolulu, where visitors can easily get stuck in hours of heavy traffic, Commute can help. Just input basic information about your destination and expected leaving time, and the app will start sending you traffic information 15 minutes before you leave. Testing Commute proved to be a challenge for me, because my home address is about 900 miles from my place of work. But if you have only a short distance to travel through a heavily populated area, you can use Commute to avoid traffic jams. Another source of travel-related problems is money. Thats particularly true when youre dealing with a foreign currency. The latest Travel Money Tracker helps travelers prevent currency mix-ups. It immediately changes a countrys native currency to yours, so you know exactly how much that Espresso (濃咖啡) in Milan costs in dollars. It can also warn you when youre overspending, which can sometimes be a problem when youre on vacation. The only catch, of course, is that you have to remember to record all your purchases. Taken together, these apps solve some of the most mon travel problems. But not all of them. Some things, no smartphone can fix, which means I get to keep my job for now at least. 12. What does the writer want to tell through the example of Judy Williams? A. The cost of Blu Hotel was higher than that of others. B. The clerk was very friendly and patient. C. The smartphones have many functions. D. Technology can make our trips better. 13. Commute is not suitable for those who_. A. have a long journey B. go on the same trip every day C. can easily get stuck in traffic jams D. travel a short distance downtown 14. What is the function of Travel Money Tracker? A. It tells people how much Espresso costs. B. It warns people when they are shopping. C. It changes the native currency to yours. D. It records all peoples purchases. 15. What is the purpose of this passage? A. To encourage people to travel. C. To help people with technology problems. D. To provide people with traveling information. 第二節(jié)（共5 小題；每小題2 分，滿分10 分） 根據(jù)短文內(nèi)容，從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。 Is bottled water better for you than tap?
